Sure, it is what you endure after facing your fear. Been shy is kind of common,let me say it's just view people that don't shy like that.
When I was in primary school,same thing happened to me but I have to faced it in primary 4 and I fought, even when I got to higher institution and I wanted to go for a post in school, i have to face the whole faculty and talk but I was scared and fear came but I face it and talk and since then, there no where I can't stand and talk, what I do is that I took control of the place I want to talk and dominate, so they will have to follow me and listen to me attentively. Thank you buddy,stay blessed
